Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00049 | $0.00787 |
| Opus 5.5 | $0.00020 | $0.00315 |
| Sonnet 5.5 | $0.00010 | $0.00157 |
| Haiku 4.5 | $0.00005 | $0.00079 |
Grade A, and why
change-impact-analysis scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Change Impact Analysis
Use this skill to run Change Impact Analysis as a practical consulting method, not as a generic framework explanation.
Method Notes
- Describe current-to-future behavior changes by affected group.
- Assess impact severity, readiness, capability gap, and resistance.
Required Inputs
Collect or infer these inputs before execution:
- change description
- affected groups
- current vs future process
- adoption constraints
If an input is missing, do not block automatically. Mark it as missing, state the assumption used, and add a validation action.
When Not To Use
Do not use before the proposed change, affected groups, processes, systems, locations, and timing are defined. It identifies what must adapt; it does not replace a delivery plan or risk assessment.
Adjacent Methods
force-field-analysis: compare forces supporting and resisting a defined change.raci-matrix: assign responsibility after the work and decisions are clear.communications-plan: design audience messages, channels, cadence, and feedback.
Step-by-Step Execution
| Step | Required input | How to execute | Output |
|---|---|---|---|
| Define change | Current state, future state, go-live date. | State what will change in work, decisions, tools, or incentives. | Change definition. |
| Identify affected groups | Teams, roles, customers, partners, stakeholders. | List who is affected and how. | Affected group map. |
| Assess impact | Current/future workflows, workload, capability, readiness. | Rate impact severity, readiness, resistance, and capability gap. | Impact assessment. |
| Design support | Impact assessment. | Define communication, training, sponsor, process, system, or policy support. | Adoption support plan. |
| Plan rollout controls | Support plan, timing, risks. | Set owner, cadence, feedback loop, and escalation path. | Change rollout plan. |

What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

change-impact-analysis is a skill published in the GitHub repository fzfclee/consulting-skills (7 stars, last pushed 15d ago), licensed Apache-2.0. It adds 49 tokens to every session and 787 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.

apply-insight-synthesis
Use when you've gathered a substantial body of research or data and are about to write up or present it — stop gathering, cluster the findings by underlying pattern rather than by source or chronology, and repeatedly ask "so what does this mean for the decision" until you reach a small number of specific, actionable…
taxue
A main entry point for a decision-support system that asks questions, clarifies what you really need, and guides you toward an action.
taxue-learn
A learning method that turns information into usable understanding through four stages of practice and internalisation. It includes approaches such as the Feynman technique, which means explaining an idea simply to test your understanding.
taxue-diagnosis
A structured diagnosis method that examines a situation through quick, detailed, or multiple-perspective reviews. It covers life planning, business viability, business models, and possible blind spots.
taxue-job-search
A job-listing search service that looks for real open positions by location, education requirements, and employer type, then checks information across multiple sources.
taxue-solve
A thinking aid that turns a vague problem or difficult choice into a clear plan of action. It first examines what the real problem is, including whether emotions are hiding the main question.
